Fig. '7 is a perspective 65 One object of the invention is to provide an of the finished ax head. improved method of forming a forged ax head The improved method consists in first heating of the aforementioned type which is generally an a pair of bars or pieces 10 of suitable metal, improvement upon previously employed methods such as steel, to render them ductile for forgu and results in the production of an improved i h n f r i the bars between a p r f i s 7 and exceptionally strong, durable, double bladed 11 and 12 into shap to form e p of p ax head, mental poll sides.

If desired ribs 13 may a part of this specification or disclosure and in be forged on the inner faces 13 of the poll sides which like numerals of reference denote correin order to interlock with the handle when the sponding parts throughout the several views: latter is driven into the socket.

Fig. 1 is a perspective of a bar of metal from In practice, it is customary to stamp a tradewhich one of the poll sides of the ax head is name or mark on the sides of the ax head, and this can be conveniently done before the poll sides are welded together, and while the metal is somewhat ductile after the forging operation. If desired the poll sides may be forged or shaped by rolling a long bar or strip of metal into the proper crosssectional shape and then shearing the rolled bar into sections each adapted, and of the required length, to form one of the poll sides. The poll sides and blades may then be welded together as hereinbefore described.

The ribs 14 on the poll sides are only of sumcient area or height to provide sufiicient metal for joining the poll sides together by weld joints above and below the handle socket and to close the ends of the socket, so that the blades will be joined to the poll close to the socket and form substantially all portions of the ax head which are subjected to wear in cutting. This also makes it possible to join the blades to the ribs and to join the entire area of the meeting faces of the ribs by single electric welding operations and thus avoid separate operations for that purpose.

The invention exemplifies a method of making ax head in which the poll of the head is formed of separate side pieces, so that no punching or piercing of the poll is necessary for socket-forming purposes; in which the shaping of the poll sides is simple and can be quickly performed so that only a single heating is necessary; in which the brand marking can be readily performed before the roll sides are welded together; in which the waste of metal is reduced to a minimum; in which simple dies can be used for the various parts in which locking ribs for the ax handle can be readily forged on the inner faces of the poll sides; and by which the head can be produced at a low cost.

The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claim, without departing from the spirit and scope of the invention.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is:

That improvement in the manufacture of double bladed, forged ax heads which consists first in drop forging separate pieces of heated metal to form a pair of -complemental poll sides shaped so that when placed together they form a handle socket therebetween and having comparatively short ribs at the ends thereof adapted to abut against one another to close the ends of the socket and terminating immediately outwardly of the socket ends, then placing the poll sides together and arranging apair of substantially full length blades adjacent the ends of the socket respectivelyand in abutting relation with respect to the ribs, and finally by a single electric welding operation uniting together the abutting faces of the ribsat oneend of the handle socket and joiningto such ribs the full length blade adjacent said one end of the socket and by a second single electric welding operation uniting together the abutting faces of the ribs at the other end of the socket and joining to such ribs the full length blade adjacent said other end of the socket.
